Wood preservatives
The present invention relates to water-soluble wood preservatives for preserving, in particular, fresh wood, for example fresnly cut wood in sawmills or freshly 5 felled timber in the forest.
It is known that dimethylalkylamines, 2-Cmethoxy-carbonylamino)~benzimidazole C8CM) or N-tridecyl-2,6-di-methylmorpholine (tridemorph), for example in the form of their salts, can be used for preserving wood ( E P - 14 7 976, 10 DE-3 138 575.3 and DE-3 507 420.5). However, their actions are unsat isfactory.
We have found that wood preservatives which contain a) a dimethylalkylamine, b) a water-soluble acid and c) a water-insoluble acid or BCM or c) a water-insoluble 15 acid and 2-(methoxycarbonylamino)-benzimidarole have a very good action against wood pests, in particular fungi, the action being better than that of the known wood preservatives. The novel wood preservatives are water-soluble. They are used in the form of aqueous impregnat-20 ing solutions, which are prepared from the wood preservatives (concentrates) by dilution with water. The present invention relates both to the concentrates and to the dilute aqueous solutions (impregnating solutions) obtainable by diluting the concentrates with water. The 25 novel wood preservatives are suitable for protecting wood, in particular fresh wood, as obtained, for example, as freshly cut wood in sawmills or as freshly felled timber in the forest.
A dimethylalkylamine is an N,N-dimethyl-N-alkyl-30 amine where alkyl is, for example, of 6 to 20, preferably 12 to 14, carbon atoms. In addition to the pure di-methyla IkyI amines, it is also possible to use mixtures, for example mixtures of d i me t h y I-C i2~a ^ Y a m * ne anc^ methyl-C-14-alkylamine (dimethyl-C-ij/C-i^-alkylamine). 35 A water-soluble acid is, for example, a water-
soluble inorganic acid, for example an acid of phosphorus, in particular phosphonic acid (H3PO3), phosphinic

acid (HjPOj), acidic anosohor ic esters (eg. mono- or di-alkyl phosphate, for example monobutyl phosphate or di-butyl phosphate) or monoalkyl ptiosodonates, or an acid of sulfur, eg. a sulfonic acid, for example benzenemono-sulfonic or benrenedisulfonic acid, sulfamic acid or £ -phenolsulfonic acid, or an organic C2-C4-carboxyIic acid, for example a monocarboxylic acid, eg. acetic acid, propionic acid, methoxyacetic acid, lactic acid or glycollic acid, or poIycaroox/Iic acids, eg. fumaric acid, citric acid or maleic acid.
A water-insoluble acid is, for example, an aliphatic C5-C20~carboxy1ic acid, for example a monocarbox-ylic acid, such as hexanoic acid, heptano ic acid, octanoic acid, nonanoic acid, decanoic acid, 2-ethyIpentanoic acid, 2-ethylhexanoic acid, 2-ethylheptanoic acid, isooctanoic acid, isononanoic acid or versatic acids (highly branched .nonocarboxyl ic acids), or a dicarboxylic acid, eg. decane-dicarboxylic acid.
The acids can also be used in the form of their salts, eg. dimethylalkylamine salts. The BCM-containing agents may also contain a water-insoluble acid, in addition to the water-soluble acid.
The wood preservatives are water-miscible, form clear solutions with water and, in the usual concentration for use (from 0.5 to *0.0% by weight, based on the concentrate), have a pH of less than 7.0 when a dimethylalkylamine is used exclusively, a pH of less than 6 when mixtures of a dimethylalkylamine with tridemorph are used and a pH of less than 3.5 when mixtures of dimethylalkylamine with BCM are used. They are prepared by mixing the individual components with one another.
The wood preservatives (concentrates) are more or less viscous solutions whose viscosity can be reduced by adding polar solvents. Examples of suitable polar solvents are dimethyIf0rmamide, diethyIf0rmamide, N-methyl-pyrrolidone, dimethyl sulfoxide, glycols, polyglycols, glycol ethers, glycol ether acetates and alcohols. In
It 6 7
- 3 - 0.2. G9?5/C3C6£
these cases, the BCM salt is generally in pasty form.
The concentrates generally contain from 5.0 to 75.0, in particular from 30 to 50, X by weight of a dimethyI-C5-Cjq-a IkyLamine,
from 0 to 75.0, in particular from 15 to 25, X by weight of tridemorph,
from 0 to 25.0, in particular from 4 to 12, X by weight of SCM,
from 2.5 to 50.0, in particular from 10 to £5, X by weight of a water-soluble acid,
from 0 to 25.0, in particular from 5 to 15, X by weight of a water-ins01ubIe acid and from 0 to 50.0, in particular from 4 to 30, X by weight of a solvent,
the sum being 1002 by weight in each case. The mixing ratio (parts by weight) of BCM to dimethylalkylamine is, for example, from 1 : 50 to 2 : 1, preferably from 1 : 20 to 1 : 2.
Water, which, for example, is present in the commercial form of the acids, may also be present.
The following may additionally be used: wetting agents, corrosion inhibitors, colorants and, if required, binders.
In order to improve the range of action of the wood preservatives, they may additionally contain nitrogen-containing organic fungicides, for example further morpholine derivatives, eg. fenpropemorph or aldi-morph, guanidine derivatives, eg. dodecylguanidine, chlorhexadine or guazatine, imidazole derivatives, eg. imazalil, dodecylimidazole or glyodine, pyrimidine derivatives, eg. hexatidine, or quaternary ammonium compounds, eg. N-dodecylpyridinium chloride. Other fungicides may also be used, for example 2-(thiocyanomethy I -thio)-benzothiazo1e, 3-iodo-2-propyny I buty1 carbamate, 2-(4-thiazolyl)-benzimidazole or water-soluble salts (eg. the potassium salt) of N-cycI ohexyIdiazenium dioxide.
Other fungicides too, such as furmecyclox or
22 6 7 2 1
- £ - O.Z. C975 /CQG64.
benodanil, or insecticides, such as lindane or oerae tn-r in, can be added to the formulations and should be incorporated with or without the addition of emulsifiers, for example ox/ethylated nonylphenols. 5 Depending on the danger to which the wood is ex posed, application for preservation of the wood may be effected, for example,
a) by spraying the wood with the solution,
b> by dipping the wood into the solution, 10 c) by impregnating the wood by means of pressure differences, for example by the pressure process or double vacuum impregnat ion, or d) by spreading the preservative over the wood.
In the case of secondary wood products, for exam-*5 pie cut wood and pulp, and other industrial products or ce 11 uIose-containing materials which are susceptible to fungal attack, for example intermediates in papermak ing, ligneous annual plants (bagasse, rape), the application should be adapted to the technical possibilities. 20 The wood-preserving activity of the agents covers, for example,
a) molds (eg. Aspergillus niger),
b) fungi which cause wood rot (eg. Chaetomium globosum),
c) blue stain fungi (eg. Pullularia pullulans) and 25 d) wood-destroying 8asidiomycetes (eg. Serpula lacrymans);
in particular, the action against blue stain fungi is very good.
The wood preservatives have a very good fungici-30 dal action, as shown by the experiments below.
The experiments were carried out using fresh,
sawn pine sapwood timbers measuring 200 x 50 x 15 mm, which had been deep-frozen at the beginning of the experimen t.
After thawing out (which takes about 6 hours),
the timbers were dipped for about 10 seconds in the solutions to be applied, placed in an inclined position

to drip off, stored under a roof for about 24 hours under normal atmospheric conditions and then olaced in the test area. Ten sample boards were impregnated with each individual test solution in the manner described above. Unimpregna-5 ted control timbers were dipped into pure water.
The test area chosen was a snady meadow, whose grass was cut short before the'test timbers were laid out. The test timbers were placed on two plastic rails, at a height of about 1 cm above the grass. TO The test boards exposed to outdoor weather (rain)
were checked after two months (August/September).
The fungicidal activity was classified in four categories on the basis of the resulting discoloration and changes in the wood surface:
